I wanna use a rendering engine with QCAR (vuforia) to build an AR app. Is it possible to incorporate a rendering engine which uses OpenGL ES 1.1 with QCAR?
I QCAR is using opengl 2.0 for sample applications.
QCAR supports both 1.x and 2.0 but by default 2.0 is enable. If your rendering engine only supports 1.x you can easily tweak QCAR to use 1.x by changing this:
USE_OPENGL_ES_1_1 := false
to TRUE in Android.mk file which is located under JNI folder. I assume that you are using QCAR for Android but for iOS the steps are pretty much the same.
